Many cameras, such as single lens reflex (or SLR) cameras, include a camera body, a lens, a viewfinder, a data display, and a shutter release that actuates movement of a shutter. When taking a photo, the shutter emits a sound, such as a “click.”
Oftentimes, a still camera will be used during filming (or recording) of a motion picture or television show. However, the sound emitted from the shutter of the still camera may be picked up by the sensitive audio equipment used during filming, which can result in the need for reshoots or audio dubbing because of the sound captured on the soundtrack of the motion picture or television show. Accordingly, a need developed for the use of a housing or case that reduces the sound emitted from the camera shutter by enclosing the camera. Housings of this type are sometimes referred to as “sound blimps.”
Although sound blimps have been known in the art since the mid-1960s, the sound blimps of the prior art are often made of metal, sometimes requiring multiple layers, which resulted in an expensive to manufacture and heavy design. Prior art sound blimps also would typically require the use of a remote control to actuate the shutter release button. Further, the prior art sound blimp did not provide any means for using features on the camera other than the shutter release or autofocus because additional openings in the sound blimp would diminish the sound dampening properties of the sound blimp.
One or more aspects of the present disclosure include a housing for operating a camera that is made of a lightweight rubber or rubber-like material. One or more aspects of the present disclosure are directed to a housing that allows a user to use various features of the camera without compromising or significantly compromising sound dampening qualities.
According to one or more embodiments, a housing for operating a camera having a lens and a camera body includes a main portion defining a cavity for receiving the camera body, wherein the main portion has a front wall and a rear opening, and a closure portion releasably connected to the main portion to close the rear opening. The front wall has a lens opening for receiving the camera lens when the camera is within the cavity of the main portion, and the housing includes a homogeneous mass of rubber having a thickness of at least ⅛ inch.
In some embodiments, the housing has a glassy transition temperature of between about −43 C and about −73 C.
In more detailed embodiments, the front wall has a thickness of at least ⅛ inch.
In some embodiments, the front wall has a thickness of between about ¼ inch and about ½ inch.
In some embodiments, the thickness of the front wall is ⅜ inch.
In some embodiments, the material of the housing is an ethylene propylene diene monomer (EPDM) rubber.
In some embodiments, the closure portion includes a closure wall and an edge portion extending around the perimeter of the closure wall and away from the closure wall in a direction perpendicular to the closure wall.
In some embodiments, the main portion includes a top wall, a bottom wall, and two side walls, each including a first profiled edge portion, and the peripheral portion of the closure wall includes a second profiled edge portion, wherein the first profiled edge portion is complementary to the second profiled edge portion.
In some embodiments, one of the first and second profiled edge portions is a rib and the other of the first and second profiled edge portions is a groove.
In some embodiments, the bottom wall has a thickness of ½ inch.
In some embodiments, the main portion and the closure portion are connected by a hinge.
In some embodiments, the hinge is recessed into the housing.
In some embodiments, the housing further includes a recess in a bottom surface of the housing.
In some embodiments, the recess includes a threaded opening.
In some embodiments, the housing further includes a non-axisymmetric threaded adapter sized to fit inside the recess of the housing.
In some embodiments, the housing further includes a flange surrounding the lens opening and extending away from the housing.
In some embodiments, the flange includes a notch in a lower portion thereof.
In some embodiments, the housing further includes one or more retainers connected to the flange and configured to maintain contact between a lens tube and the flange.
In some embodiments, the main portion further includes a shutter through-hole and the housing further includes a shutter button configured to engage a shutter release on the camera.
In some embodiments, the closure wall further includes a first protrusion protruding from an inner surface of the closure wall to engage a first button on the camera body when the camera is in the housing and when the rear opening is closed.
In some embodiments, the closure wall further includes a second protrusion protruding from an inner surface of the closure wall to engage a second button on the camera body when the camera is in the housing and when the rear opening is closed.
In some embodiments, a portion of the closure wall surrounding the first protrusion is thinner than adjacent portions of the closure wall.
In some embodiments, the portion of the closure wall surrounding the first protrusion is a first protrusion groove.
In some embodiments, the main portion includes a top wall having a utility bar connected thereto.
In some embodiments, the utility bar comprises a plurality of shoes for mounting accessories to the housing.
In some embodiments, the main portion includes a slidable side panel that is removable to expose a side of the camera body when the camera is in the housing and when the rear opening is closed.
These and other features and aspects of embodiments of the present disclosure will be better understood by reference to the following detailed description, when considered in conjunction with the accompanying drawings. Like numbers are used throughout the figures to reference like features and components.
Referring now to an example embodiment illustrated in
The closure portion 36 has a closure wall 40 that is opposite to the front wall 32 when the rear opening 34 is closed. The closure wall 40 may include a first protrusion 42 that corresponds to an autofocus button, or other similar button, on the camera body 26. As such, when a user applies pressure to the closure wall 40 in the area of the first protrusion 42, the first protrusion 42 may engage the autofocus button, or other similar button. The closure wall 40 may include a second protrusion 44 that corresponds to a navigation button, or other similar button, on the camera body 26. As such, when a user applies pressure to the closure wall 40 in the area of the second protrusion 44, the second protrusion 44 may engage the navigation button, or other similar button. The closure wall 40 may include a viewfinder window 46 and may include a screen window 48. The viewfinder window 46 aligns with a viewfinder on the camera body 26 and the screen window 48 aligns with a screen, for example an LCD panel, on the camera body 26.
The front wall 32 may include a flange 50 (e.g., a lens tube flange) that corresponds to the lens opening 38. The flange 50 may be configured to receive a lens cover or a lens hood or a lens tube 52, as illustrated in
The main portion 28 may also include a utility bar 60. The utility bar 60 may be mounted on a top wall 29 of the main portion 28, and may include one or more shoes 62 that are configured to hold various camera accessories, for example, a lens shade, a French Flag, a GOPRO camera, etc.
The housing 20 may be adapted to be mounted on a tripod. The housing 20 may include a removable side panel 64 (e.g., a side access panel) that may expose a side of the camera body 26. As such, a user may attach various cables to the camera body 26, such as audio/visual cables to allow a user to display images on an external screen, without removing the camera 22 from the housing 20.
The housing 20 is made of a homogeneous mass of rubber or rubber-like material. For example, the housing 20 may be made of an elastomeric material having relatively low sound damping properties and improved vibration isolation properties, such that the housing 20 has low transmissibility of sound at frequencies above the resonating frequency of the material. For example, the housing 20 may be made of a material having a relatively low ratio of viscous to elastic response and/or a relatively low glass transition temperature (Tg). If the sound emitted from the shutter of the camera 22 is at a higher frequency than the resonant frequency of the material of the housing 20, the material exhibits low transmissibility and thus the sound is dampened by the housing 20. For example, the housing 20 may be made of an elastomeric material having a Tg of −40 C or less, potentially a Tg in a range of between about −43 C and −73 C, and in one particular embodiment, a Tg of −65 C. Some examples of suitable materials include ethylene propylene diene monomer (EPDM) rubber, ethylene propylene (EPM) rubber, natural rubber (NR), and styrene butadiene rubber (SBR), but the present disclosure is not limited thereto. In one or more embodiments, the housing 20 is made of EPDM rubber. In one or more embodiments, the housing 20 is made of a thermosetting elastomer.
Referring now to an example embodiment illustrated in
The housing 20 is movable between a closed configuration, illustrated in
The closure portion 36 includes the closure wall 40 (i.e., a rear wall of the housing 20). The closure wall 40 may have a substantially rectangular face. The closure portion 36 may further include an edge portion or a peripheral portion 37 that may extend along the entire perimeter of the closure wall 40, and may extend away from the face of the closure wall 40 in a direction perpendicular to the closure wall 40. For example, when the housing 20 is in the closed configuration, the substantially rectangular closure wall 40 may extend in the first direction X and the second direction Y, and the edge portion 37 may extend in the third direction Z. In one or more embodiments, the main portion 28 and the closure portion 36 may have rounded or beveled edges, as illustrated in
In one or more embodiments, the housing 20 may have a uniform or substantially uniform thickness. In other words, each wall of the main portion 28 and the closure portion 36 may have the same thickness. In other embodiments, the thicknesses of the walls of the housing 20 may vary. For example, in one or more embodiments, the thickness of the top wall 29 may be greater than the thickness of the bottom wall 31. The thickness of the edge portion 37 may vary according to the thickness of the walls of the main portion 28. For example, in embodiments where the thickness of the top wall 29 is greater than the thickness of the bottom wall 31, a thickness of a top portion of the edge portion 37 will be greater than a thickness of a bottom portion of the edge portion 37. In one or more embodiments, the thickness of the housing 20 may range from between about ¼ inch to about 1 inch, preferably between about ⅜ inch to ⅝ inch, and more preferably between about ⅜ inch and about ½ inch. In one or more embodiments, the thickness of the bottom wall 31 may range from between about ¼ inch to about 1 inch, preferably between about ⅜ inch to ⅝ inch, and more preferably about ½ inch, and the thickness of the front wall may range from about ⅛ inch to about ¾ inch, preferably between about ¼ inch to about ⅝ inch, and more preferably about ⅜ inch.
As discussed above, the housing 20 provides sound dampening qualities. In order to minimize or reduce the amount of sound that escapes from the housing 20, the main portion 28 and the closure portion 36 may be sealed together when in the closed configuration. Referring to
In some embodiments, the housing 20 may omit the groove 39 and the rib 33. In some embodiments, the rib 33 and the groove 39 may be discontinuous, or may extend around only a portion of the corresponding first and second profiled edge portions. For example, the rib 33 may extend from the top wall 29, and the first and second side walls of the main portion and the groove 39 may extend along top and side portions of the edge portion 37, but not along the bottom portion of the edge portion 37.
The main portion 28 and the closure portion 36 may be attached together, thereby substantially enclosing the cavity 30 and covering the rear opening 34, and the main portion 28 and the closure portion 36 may be separated or substantially separated, thereby exposing the cavity 30 and the rear opening 34. When the rear opening 34 is exposed, or not covered by the closure portion 36, the camera 22 may be placed inside of the housing 20 (i.e., may be placed inside of the cavity 30 through the rear opening 34).
The main portion 28 and the closure portion 36 may then be closed, or securely attached, thereby enclosing or housing the camera 22 inside the housing 20. In some embodiments, as illustrated in
In one or more embodiments, the main portion 28 and the closure portion 36 may be connected by the hinge 35. For example, the bottom wall 31 and the bottom portion of the edge portion 37 may be connected by the hinge 35. Accordingly, the main portion 28 and the closure portion 36 may be rotatable or pivotable about the hinge 35, thereby exposing or covering the cavity 30 and the rear opening 34. In one or more embodiments, the housing 20 may omit the hinge and the main portion 28 and the closure portion 36 may be completely separable. In one or more embodiments, the hinge 35 may facilitate rotation of the main portion 28 and the closure portion 36 about a top or a side of the housing 20.
The main portion 28 may include a latching member 66 (e.g., a top latch snap member) and the closure portion 36 may further include a complementary latching member 68 (e.g., a top latch post) that mates with the latching member 66. As such, when the housing 20 is in a closed position, the latching member 66 and the complementary latching member 68 may latch together. The latching member 66 and the complementary latching member 68 may be any suitable means for fastening, for example, a compression latch or an over-center clasp pivotally attached to the main portion 28 to engage a protrusion on the closure portion 36. In some embodiments, the housing 20 may omit the latching member 66 and the complementary latching member 68. For example, in one or more embodiments, the rib 33 and the groove 39 may essentially function as a latch and the latching member 66 and the complementary latching member 68 may be omitted.
In some embodiments, the main portion 28 and the closure portion 36 may be releasably attachable by a plurality of latching members 66, 68. For example, the top wall 29 may include a first latching member 66 and the first side wall may include a first complementary latching member 68, and the bottom wall 31 may include a second latching member 66 and the bottom portion of the edge portion 37 may include a second complementary latching member 68 that mates with the second latching member 66. In some embodiments, the housing 20 may include three, four, or more latching members 450. The latching members may be located on various walls (or sides) of the main portion 28 and the closure portion 36, and each side may include more than one latching member 66. For example, the top wall 29 may include a third latching member 66 and the top portion of the edge portion 37 may include a third complementary latching member 68 that mates with the third latching member 66. In one or more embodiments, the housing 20 may include the hinge 35, the first latching member 66 on the top wall 29, the first complementary latching member 68 on the top portion of the edge portion 37, the second latching member 66 on the top wall 29 and spaced apart from the first latching member 66, and the second complementary latching member 68 on the top portion of the edge portion 37, spaced apart from the first complementary latching member 68.

In one or more embodiments, the bottom wall 31 of the main portion 28 may have a bottom opening 72 that accommodates an adapter (e.g., a threaded adapter) 74, as illustrated in
As illustrated in
The front wall 32 may further include a flange 50. For example, an outer surface of the front wall 32 may include the flange 50. The flange 50 may extend away from the housing 20 (e.g., may longitudinally extend from the outer surface of the front wall 32 in the third direction Z). The flange 50 may correspond to the lens opening 38 and may generally surround the lens opening 38. The flange 50 may be generally circular, but the present invention is not limited thereto, and the flange 50 may be any suitable shape such that the lens 24 of the camera 22 may function properly and/or may be inserted through the lens opening 38.
Referring to
The retainers 51 may be attached to the outer edge of the flange 50 (i.e., the flange 50 may be between the retainers 51 and the housing 20). Each retainer 51 may be rotatable about an axis extending in the third direction Z. In one or more embodiments, the retainer 51 may have a flat outer surface, a flat inner surface adjacent the flange 50, three flat side surfaces, and a curved side surface. The curved side surface may be defined by an arcuate groove that provides a relatively simple interface between a user's finger and the retainer 51 so that a user may easily rotate or pivot the retainers 51. However, the shape of the retainers 51 is not limited thereto, and the retainers 51 may have any suitable shape. The retainers 51 may each be aligned on the flange 50 such that in a first orientation, one of the three flat side surfaces does not overlap with the lens opening 38, and in a second orientation, at least a portion of the retainer 51 overlaps with the lens opening 38, thereby securing the lens hood or lens tube 52 to the flange 50, and minimizing the likelihood of the lens hood or lens tube 52 becoming separated from the flange 50.
In one or more embodiments, the flange 50 further includes the notch 54. As illustrated in

In one or more embodiments, the closure wall 40 may include the second protrusion 44. The second protrusion 44 may correspond to a navigation button or other button on the camera body 26. Much like the first protrusion 42, the second protrusion 44 may protrude from the inner surface of the closure wall 40 and toward the cavity 30 when the housing 20 is in the closed configuration. The second protrusion 44 may be surrounded by a second protrusion groove 45. The outer surface of the closure wall 40 may include a second protuberance 47 that corresponds to the second protrusion 44. The same principles discussed above with reference to the first protrusion 42 may be applied to the second protrusion 44, so additional description of the second protrusion 44 is omitted herein.

Also referring to
In one or more embodiments, the housing 20 may include the screen window 48 and the second protrusion 44. The second protrusion 44 may be positioned adjacent the screen window 48 so that the second protrusion 44 may be used to engage a navigation button adjacent a screen of the camera 22.
In one or more embodiments, the housing 20 may include the utility bar 60. For example, the utility bar 60 may be mounted onto the top wall 29 of the main portion 28, as illustrated in
Referring to
When the side panel 64 is removed from the housing 20, a user may access the side of the camera body 26, thereby allowing the user to attach various cables to the camera body 26, for example audio/visual cables. Although the side panel 64 is referred to as a “side” panel, the side panel 64 may be located in any suitable wall of the housing 20 such that it corresponds to a portion of the camera body 26 to which audio/visual cables and other cables may be attached.
In one or more embodiments, the housing 20 may include a material inside the housing 20 to support and to snugly align the camera body 26 inside the housing 20. For example, the housing 20 may include one or more pieces of a foam material affixed to an inner surface of the front wall 32 inside the cavity 30. The material may provide additional sound dampening qualities, and may help to properly align the camera body 26 once it has been inserted into the rear opening 34. For example, the material may extend in the third direction Z and may prevent the camera body 26 from contacting the front wall 32, thereby improving the likelihood that the camera body 26 is properly aligned in the housing 20, and allowing a user to utilize various features of the housing 20, for example, to utilize the first protrusion 42 even if a user decides to point the housing 20 with the camera 22 in a downward direction.
